This paper deals with the lumped-parameter modelling of magnetically linear eddy-current devices which have one terminal voltage and current. The device is first characterised by means of frequency-domain finite-element (FE) computations considering the relevant frequency band, for subsequently fitting constant-coefficient RL ladder circuits of various extent (i.e. number of branches). The accuracy of the ladder-circuit model is assessed in both frequency and time domain. This is successfully applied to the axisymmetric magnetic levitation device of TEAM Workshop problem 28.
